I didn’t notice that Camila is the one that realized Melanie’s story. And she gave the book and look smiling at Ava and Beatrice

And another anon:

I thinks camila knows 

Yeah! I really liked that little moment from her and how much it conveyed, not only that people knew, but they didn’t all disapprove. And I do think she knew, it was too deliberate and specific to mean anything else. I don’t imagine they’d ever talked about it before, but she leapt at the chance to show Beatrice that not only was a previous halo-bearer a lesbian, the halo actually got more powerful when she accepted what she was.
